The disk needs to be partitioned and formatted.

Drive Preparation - El Capitan or Later

Open Disk Utility in the Utilities' folder.
After Disk Utility loads select the drive (out-dented entry with the mfgr.'s ID and size) from the side list.
Click on the Erase button in the Disk Utility toolbar. A panel should drop down.
In the drop down panel set the partition scheme to GUID. Set the Format type to APFS (SSDs only) or Mac OS Extended (Journaled.)
Click on the Apply button and click on the Done button when it is activated.
Quit Disk Utility.
